In C++ Important Coding Guidelines: Use comments, and whitespaces around operators and assignments. Use line breaks and indent your code. Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code. Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable. Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
write a C++ program. Write a program that calculates and displays the average of a group of test scores, all integers, after the lowest score in the group has been dropped. There are six test scores in the group. The program must contain only the following functions in additionto the main:• void getScore should ask the user for a test score, store it in a referenceparameter variable, and validate it. This function should be called by the mainfunction once for of the six scores to be entered by the user.• double calcAverage should calculate and return the average of the five highest scores. This function should be called just once by the main function, and should be passed the six scores. Use pass by reference to receive the lowest test score.• int findLowest should find and return the lowest of the six scores passed to it. It must be called by the calcAverage function, which uses it to determine which of the six scores to drop.• void displayResults should be called by the main function…
Write a C++ program to calculate a rectangle's area. The program consists of the following function: getLength - This function should ask the user to enter the rectangle's length. and then returns that value as a double • getWidth - This function should ask the user to enter the rectangle's width. and then returns that value as a double. • get Area - This function should accept the rectangle's length and width as arguments and return the rectangle's area. • displayData - This function should accept the rectangle's length, width and area as arguments, and display them in an appropriate message on the screen. main - This function consists of calls to the above functions.

Instructions: Write a program in C++ that uses 2 different functions to compute who would win in a game of Rock Paper Scissors. Each function will use different Boolean Expressions to compute who won. The Boolean Expressions can use arithmetic operators as long as the expressions result in a 1 or a 0. Both functions will take as input, 2 integers as arguments: Player_1- This can be 0, 1, or 2 Player_2- This can be 0, 1, or 2 0=Rock 1=Paper 2=Scissors The functions will return an integer value to indicate a tie or which player won Return Value 0 1 2 Meaning Tie Player 1 Won Player 2 Won Run both functions in separate loops. Output how long it took to run both functions. Note: Both functions need to take in the same exact inputs for every loop iteration.
C++ only Upvote for your own work and correct answer/ Downvote for copying the answer from a different website. It must be in C++ and it must be a working code. It needs to follow the required directions for example: MAKE SURE IT POINTS OUT EVERY TIME THE STATEMENT IS INVALID IF IT IS INDEED INVALID. Thank You. Assignment: Create a C++ program that can test the validity of propositional logic. Remember, a propositional logical statement is invalid should you find any combination of input where the PROPOSITIONAL statements are ALL true, while the CONCLUSION statement is false. Propositional Statements: If someone has a rocket, that implies they’re an astronaut. If someone is an astronaut, that implies they’re highly trained. If someone is highly trained, that implies they’re educated. Conclusion Statement: A person is educated, which implies they have a rocket. Your output should declare the statement to either be valid or invalid. If it’s invalid, it needs to state which combination…

Write C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.
Using C++; Define a struct, fruitType, to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int). Write a program that declares a variable of type fruitType, prompts the user to input data about a fruit, and outputs the fruit data.
I want the solution in C++ language i want the solution related to chapter 4 in the 10th edition of the textbook Solving the problems with C++. Also i want the solution that setups the midnight time to 0, and lists all the scenarios (possibilities) from that time and future time within 24 hrs. 4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; // You can also use a char, i.e. A or P for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50, isAM = false or if using a char, hours =…
Write a C++ program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. **DO NOT USE AN ARRAY OR GLOBAL VARIABLES!!!*** YOU MUST USE THE STATED FUNCTIONS. AND INPUT VALIDATION. For FULL CREDIT DISPLAY THE LOWEST SCORE WITH GOOD OUTPUT DESCRIPTION you MUST USE function prototyping.. DO NOT ACCEPT SCORES LESS THAN 0 OR GREATER THAN…
